VEHICLE-TOP.

SPECIFICATION forming part of Letters Applieaiioirled January 31, 1884.

To @ZZ whom it may concern:

.Be it known that I, JACOB SEBASTIAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and usefulImprovements in \Vagon-T0p Clamps, of which the following is a specification, reference being had therein to the accompany` ing drawings.

This invention relates to clamps for adjusting wagon-tops to different angles or positions; and it consists in the novel feature of construetion, hereinafter described,whereby au article of superior utility is obtained.

In the accompanying drawings, Figure l is a cross-section of a clamp embodying my invention. Fig. 2is aside view thereof. Fig. 3 is a detail view.

Similar letters indicate similar parts.

The letters A B designate two disks of metal or other rigid material facing each other, to each or" which disks is attached an elastic washer, C orD, by rivets s, or other suitable means. These washers C D are preferably made of india-rubber, although leather or other material of similar nature may also be used, andthe position of the washers is on the opposite surfaces of the disks,where thewashers are in superficial contact with each other. The disksA B are united by means of an axial screw-bolt, E, which passes through them and thc washers, it acting on one of the disks by means of. its head E and on the other by means of the nut G, the latter beinga thumb nut; and when this nut is set toloosenthebolt, the disks may turn freely on it,while, when the nut is set to tighten the bolt, the disks are thereby rmly clamped to each other, so that Patent No. 303,461, dared August 12, 1884.

(No model.)

'the parts connected to the disks preserve a iiXed relation to each other.

In applying the device to a wagon-top,'the seat-arm II is secured to either disk, and the bow-arm I to the other disk, on the outer surface thereof, by rivets or other suitable means, and the seat-arm bcingnow properly mounted on the wagonseat, the bow-arm, together with the top, may be adjusted to any desired angle or position by means of the disks, one of the disks turning and the other remaining stationary. The arms II I intersect the screwbolt E, they being provided, like the disks and washers,with holes forthe passage of the bolt, and hence the disks are relieved from undiametric strain.v Either of the disks A B is provided with a iiange, o, to overlap the edge of the'other disk, thereby protecting the elastic washers against dust, grit, and other deleterious substances.

I claiml. rIhe combination, substantially as. hereinbfore described, of the rigid disks, having their opposed surfaces provided with attached elastic washers and the axial screw-bolt uniting the disks.

2. The combination, substantially as hcreinbefore described,l of the rigid disks, having their opposed surfaces providedwith attached elastic washers, the axial screwbolt uniting the disks, and the seat-arm and bow-arm seeuredto the disks, respectively.
